Hip joint instability in breech pregnancy.

222 consecutive fetuses found by ultrasound to be in breech presentation in the 33rd gestational week were followed with repeated examinations in weeks 35 and 38. Ninety-one of these fetuses persisted in breech presentation until delivery, while cephalic version occurred in 131. The frequency of hip joint instability was 21% in the breech delivered group and 1.5% in the vertex delivered group. The position of the fetal legs was established at each ultrasound examination. The intrauterine fetal attitude was classified as extended when the fetuses had extended knees and maximally flexed hips at all ultrasound examinations. This occurred in 30 breech delivered fetuses, 47% of which developed hip joint instability. Only 8% of the breech born infants with flexed legs in utero developed hip joint instability. It is concluded that instability of the hip joint is a consequence of the intrauterine attitude, rather than of the breech delivery per se.

Neonatal chlamydial conjunctivitis.

Maternal chlamydial antibodies were determined in cord sera of 41 infants who developed neonatal chlamydial conjunctivitis and compared with the antibody profile of infants who had been exposed to Chlamydia trachomatis at birth by their isolation positive mothers but in whom conjunctivitis did not develop. No protective effect could be attributed to maternal antibodies transferred to the infants. Paired sera samples were collected from 18 infants with chlamydial conjunctivitis. Chlamydial IgM antibodies were detected in four of these 18 cases at the time diagnosis was established by isolation. An additional eight cases had developed chlamydial IgM at the time the convalescent sera samples were taken, on average on day 40. At that time symptoms had disappeared after systemic treatment had been given. Thus chlamydial IgM antibodies were eventually shown in two thirds of infants with chlamydial conjunctivitis who were all systemically treated and clinically healed. These data suggest a cautious assessment of chlamydial IgM in the diagnosis of chlamydial pneumonia.

Growth in breech presentation. Ultrasound and post-partal assessment of growth in 225 fetuses presenting by the breech in the 33rd gestational week.

225 fetuses with ultrasonically determined gestational age were shown by ultrasound to be in breech presentation in the 33rd gestational week. The biparietal diameter (BPD) and the mean of two perpendicular abdominal diameters (AD) were measured ultrasonically in gestational weeks 33, 35, and 38. Based on these measurements, fetal weight was estimated and compared with weight, length, and head circumference at birth and at 18 months of age. 42% of the fetuses were born in breech presentation (breech group) and 58% in vertex presentation (vertex group). The mean birth weight corrected for gestational age was 4.9% lower in the breech group than in the vertex group, which corresponds to the lower intra-uterine values of BPD and AD found in the breech group. The weight differences at birth still persisted at 18 months of age. There were no differences between the groups regarding head circumference or length, either at birth or at 18 months of age.

Group B streptococci at delivery: high count in urine increases risk for neonatal colonization.

Of 858 pregnant women studied in matched rectal, urethral and urine cultured specimens, 186 (22%) were found to be colonized by group B streptococci (GBS). GBS were detected significantly more often in rectal specimens (159) than in urethral specimens (108) or in urine specimens (64). This is supporting evidence for the gastrointestinal tract as the main habitat of GBS. Of 1786 women whose urine was sampled at delivery, GBS were isolated from 128 (7%), in 22 of whom (1% of the total) GBS were present in quantities greater than or equal to 10(4) colony forming units (cfu)/ml urine. Neonates born to women with greater than or equal to 10(4) cfu GBS/ml urine were apparently at greater risk for neonatal infection, as they were more commonly and more heavily colonized than were the newborns of women with lower quantities of GBS in urine, or if positive urethral or rectal specimens were considered. The incidence of preterm delivery or obstetric infection was not higher among women in whom GBS were isolated in specimens from any of the 3 sites; foetal distress was more common among their children, but not neonatal respiratory or infectious diseases of which the incidence was low and difficult to assess statistically.

Neonatal non-ketotic hyperglycinemia (NKH). Diagnoses and management in two cases.

Non-ketotic hyperglycinemia (NKH) has been differentiated as an autosomal recessive hereditary form of the hyperglycinemias with a defect in the glycine-cleavage system causing accumulation of glycine in all body fluids. A more severe neonatal form with early onset has been described and, though not curable, a fast and correct diagnosis for clinical management, parental information and genetic counselling is important. The clinical picture and diagnostic chemical analyses in two cases of the more severe neonatal form of NKH are reported.

Early neonatal sudden infant death and near death of fullterm infants in maternity wards.

In a large Swedish 2 1/2-year population of fullterm infants the incidence of early neonatal sudden death (ENSD) was 0.12 per 1000 newborn infants considered healthy at birth but presenting with sudden cardiovascular collapse between 6 and 100 hours after birth. In the total neonatal mortality the rate of ENSD was 11%. Well-known risk infants, e.g. prematurity, perinatal asphyxia, difficult delivery or congenital malformations were not included. In an inborn population of 20 123 fullterm newborns the rate of ENSD was 0.15 per 1000. In the same population near-missed ENSD occurred in 0.35 per 1000 liveborn infants. Possible causative factors were infections in 4 and anaemia in 2 cases. But in 7 of 13 infants thorough epidemiological examinations and postmortem sterile autopsies did not reveal the cause of death or near death. These are probably cases of sudden infant death syndrome hitherto unrecognized in the first days of life.

Perinatal mortality: changes in the diagnostic panorama 1974-1980.

During the period 1974-1980, all late abortions (greater than 19 completed gestational weeks) (LA), late fetal deaths (LFD) and early neonatal deaths (END) were surveyed in a continuous material of 17813 births with an ascertained gestational age established by early ultrasound fetometry. There was no maternal death during the period. The total perinatal mortality (PM) was 0.98% with an END rate of 0.51%. In about 45% of LFD no diagnosis was found. Intrapartum death was extremely rare as was END caused by asphyxia or infection. In END, death from immaturity constituted the major group in the beginning of the period, while after 1977 lethal malformations was the dominating diagnosis. There was a continuous decrease in Idiopathic Respiratory Distress Syndrome (IRDS) as a cause of END. The proportion of END in extremely premature children showed a constant decrease in the beginning of the period. No difference in sex was found in END except for lethal malformations where there was a significant male preponderance. As a consequence of a more active obstetrical care, some fetuses who would previously have been classified as LA were probably delivered liveborn, extremely premature and appeared as END. The question of where to set the limits for what should be included in PM is thus highly relevant.
